Recent Progress in Catalytic Nitrogen Fixation by Using Transition Metal-Dinitrogen Complexes

Abstract

Recent progress in catalytic nitrogen fixation by using transition metal-dinitrogen complexes is reviewed. Two effective reaction systems for the catalytic transformation of molecular dinitrogen into ammonia and ammonia equivalent such as silylamine under ambient reaction conditions have been achieved by the use of molybdenum- and iron-dinitrogen complexes as catalysts. Both reaction systems provide a new aspect in the development of novel nitrogen fixation under mild reaction conditions, instead of the Haber-Bosch process.
